Why subsidize the surfeit of wind turbines?
With an oversupply of wind turbines, why are governments subsidizing new manufacturing plants?
In recent years, China has ramped up its efforts to become a world leader in manufacturing and installation of wind turbines.
But the other side of the story is that China has also idled 40 percent of its industrial wind turbine manufacturing capacity as a result of oversupply and plummeting prices.
In Europe, the world’s largest turbine manufacturer, Vestas, announced a bond issue of 600 million euros ($807 million). This is the first bond issue in the company’s history and it was due to slow growth.
Cap and trade not the solution, climate scientist says
Fighting climate change is a huge investment opportunity but not through emissions trading and investors should instead put their money into renewables which will power the economy in the future, says a leading environmental scientist and cap and trade expert.
As yesterday’s walkout by African nations showed, getting anyone to agree on anything at the U.N. Climate Conference is easier said than done. The use of markets to address pollution is no different. Supporters of cap and trade — the system which allows companies or groups who meet their emissions targets to sell their remaining carbon credits — are out in force, but so are the groups who say the scheme prevents less responsible companies from breaking their bad habits.
Catching rays + cutting emissions
The phrase “catching a few rays” might conjure up images of lying on a sunny beach.
But Germany’s Renewable Energy Act has given that phrase a whole new meaning. I’ve discovered that you can get paid for capturing the sun’s energy on your roof, converting it into CO2-free electricity with the help of special equipment, and feeding it into the grid — and watch the investment yield handsome long-term returns.
New ‘gold rush’ buzz hits Germany over Sahara solar
A “gold-rush-like” buzz has spread across Germany in the last week over tentative plans to invest the staggering sum of 400 billion euros to harvest solar power in the Sahara for energy users across Europe and northern Africa. Even though European and Mediterranean Union leaders have been exploring and studying for several years the idea of using concentrated solar power (CSP), the Desertec proposition suddenly captivated the public’s attention a week ago when German reinsurer Munich Re announced it had invited blue chip German companies such as Deutsche Bank, Siemens and several major utilities to a July 13 meeting on the project. The 20 companies aim to sign a memorandum of understanding to found the Desertec Industrial Initiative that could be supplying 15 percent of Europe’s electricity in the decades ahead.
Germany’s deputy foreign minister, Guenter Gloser, has been the government’s point man for the project. I had the chance to talk to him about it.
Beyond hybrid green technology – tribrids, quadbrids next?
This portable electric recharging device could be a lifesaver if you break you leg on a windswept mountaintop in the middle of the night and find that your mobile phone battery is dead when you try to call for help.
Of course that’s vanishingly unlikely (and not part of the official sales pitch) but the K3 is an interesting example of “tribrid” technology - using three sources of power. You can plug it into the mains electricity, it has tiny solar panels and a micro wind turbine … Going on sale in June for $99.95, it can charge cell phones, iPods or other electronic devices. 
In Antarctic base, solar energy and 10 cm commute
On a British Antarctic research station, engineer Andy Binney (pictured above at work) and plumber Adam Gerrard have what must be one of the shortest commutes in the world – 10 cm.
Here is a picture of Andy at work — installing boilers that will be partly powered by solar energy at the Rothera research station in Antarctica — and pointing to the wall behind which he sleeps. For a story about Antarctica shifting to renewable energies, click here.
How much electricity do you use in a year?
It was a disarmingly simple question but, embarrassingly, I didn’t have a clue when first asked that 18 months ago. Even though I’d have to describe myself as a genuine tightwad when it comes to expenditures, I simply had no idea, strangely enough, about how much money my four-person household was spending on electricity — nor how much carbon dioxide was being produced.
Now, after a year of carefully tracking the daily use of electricity, I’ve discovered a bit about when and where power is being used and, in theory, saved — without much pain. It seemed like a no-brainer and it honestly was not hard to cut our consumption by 1,000 kilowatt hours in 2008 to 5,000 kWh — saving about 200 euros and 500 kg of CO2 in the process. There were only minor sacrifices: rigidly turning off “standby” switches and unused lights, pulling plugs on little-used appliances, putting in energy-efficient lightbulbs, using the washing machine sparingly and the dryer only rarely, and replacing an inefficient dishwasher with a low-energy model.
Germany’s ‘Sun King’ Asbeck explains solar power for Vatican
Every once in a while you run into someone with so much energy that you find yourself wishing you could plug something into them to tap a bit of that excess power. On a dark, cloudy December afternoon, I spoke to Frank Asbeck, the chairman of SolarWorld and dubbed the “Sonnenkoenig” (Sun King) by a leading newspaper in his native Germany for turning an idea (mass use of photovoltaic) into a multi-billion euro corporation with 2,500 employees — in little over a decade.
Asbeck, 49, easily the most entertaining chief executive I’ve met in Germany, lit up the room with a 90-minute surge of ideas, witty comments and untempered optimism about solar power — a delightful respite from the economic doom and gloom of the current era.
German power boss goes renewables route…at home too
You know the wind is changing for renewables — so to speak — when the head of Europe’s biggest power producer becomes an advocate — and then even decides to reduce his own personal reliance on fossil fuels by powering and heating his new house with photovoltaic and geothermal energies.
Wulf Bernotat, the chief executive of E.ON, admits he became rather belatedly an advocate for renewable energy, even if his company still gets the lion’s share of its 70 billion euros in annual turnover in 30 countries from burning fossil fuels. The reasons for the change of heart? It’s one answer to climate change, it’s the way the political winds were blowing, and there are profits to be made.
Bush’s climate plan: good sense, “Neanderthal”, or both?
A plan by President George W. Bush to set a distant 2025 ceiling for rising U.S. greenhouse gases has triggered criticisms by Germany that he is coming up with a “Neanderthal” solution to the problem – too little too late.
Most other delegates at 17-nation U.S.-led climate talks in Paris on Thursday and Friday have been far less damning, welcoming the fact that Bush is setting a ceiling for emissions, albeit one that will be a generation after most other rich nations.
